IN THE TREATMENT OF THE DYNAMIC PROBLEMS OF STRUCTURES, TWO ALTERNATE TESTING METHODS, BASED ON EXTERNAL AND EMBEDDED SENSORS, EXIST IN THE LITERATURE. IF THE SENSORS RESPOND TO THE CHANGES IN THE DYNAMIC CHARACTERISTICS OF THE STRUCTURE, AND/OR THE ENVIRONMENT, THEN THEY ARE REFERRED TO "SMART" STRUCTURES. SMART SENSORS AND SMART MATERIALS HAVE BEEN USED FOR DETECTING STRUCTURAL DAMAGES AND/OR CO ...

A novel method for preparing carbon electrode structures having applications in electrochemical double layer capacitors (EDLCs) is described. The method for preparing these structures employs carbon (graphite) nano fiber materials and results in an electrode having both high surface area and high electronic conductivity; two essential characteristics for EDLC electrodes. The fabrication process ...

This program proposes to demonstrate an ultra-low power design methodology and circuits for digital logic employing advanced dynamic voltage scaling (DVS) for asynchronous NULL Convention Logic (NCL) circuits operating in sub-threshold to super-threshold voltage regimes. The power supply voltages of logic block partitions will be independently set by on-chip voltage controllers based on the data p ...

This project is based on a novel computer graphics technology for man/machine interfaces that relies on machine learning techniques, neural-like networks, and object recognition IU techniques. The key idea is to use a few "example" views of an object or person, to teach the computer to generate other views, under user control. WIth our technology we will develop an interactive (multimedia) interfa ...

Investment castings have well served both the military and commercial markets in such areas as waveguides and splitters for microwave applications, and for connectors, housings, heat sinks and mechanical parts for electronics, optical, instrumentation, and medical devices. Tomorrow's higher RF millimeter wave and communications electronics products, and more compact optical, instrumentation and m ...

In order to maintain our nation’s technological superiority on air, sea and land, we must respond quicker to emerging threats and reduce the cost of major sensing platforms. Every DoD platform developed nowadays contains at least one sensor, whether it be RF, EO/IR, or acoustic. In fact, in a lot of recent developments, the platform is built around the sensor and exists only to support the senso ...

THIS PROPOSAL DESCRIBES A PROGRAM FOR THE DEVELOPMENT OF SUPERIOR SEA WATER BATTERIES INCORPORATING RAPIDLY SOLIDIFIED AMORPHOUS PALLADIUM-SILICON CATHODES AND RAPIDLY SOLIDIFIED CRYSTALLINE ALUMINUM ALLOY ANODES. THE SEA WATERBATTERY PERFORMANCE WILL BE EVALUATED AND THE CORROSION CHARACTERISTICS OF THE ANODE WILL BE CORRELATED WITH THE MICROSTRUCTURE AND ALLOY COMPOSITION OF THE ANODE MATERIAL. ...

REVERSE ENGINEERING DERIVES THE SPECIFICATION OFA SOFTWARE SYSTEM FROM ITS IMPLEMENTATION. IT REQUIRES BOTH A SPECIFICATION LANGUAGE AND A SET OF TOOLS. AS OUR SPECIFICATION LANGUAGE WEUSE SEDL; AS OUR INPUT LANGUAGE WE USE C; AND AS OUR PROTOTYPE WORKING ENVIRONMENT WE USE ARCADIA. SEDL, A SOFTWARE ENGINEERING DESIGN LANGUAGE DEVELOPED AT IBM, IS AN EXTENSION TO ADA THAT PROVIDES HIGH-LEVEL DICTI ...
